The results of obtaining ceramic elastically stiff and elastically resilient capillary-porous structures are presented, and the possibility of modifying them into thin-layer semi-permeable membranes with filtration properties is investigated. It is determined that the most effective technological methods for fabricating ceramic membranes based on spondilovaya clay and calcium-phosphate materials are semi-dry multistep pressing of the initial powders and casting from suspensions. A comparative investigation of the elastically stiff membranes consisting of two basic compositions is performed, and it is established that a capillary-porous structure is present and that the values of their gas permeability and the rate of filtration are close. The investigation of elastically resilient resorbable and semi-resorbable membranes based on biogenic hydroxyapatite showed that these materials have promise for applications in medicine.
